It would be easy enough for the delay simulator to enable/disable promiscuous
mode. But it’s handy to bridge the pipes: traffic flows whether or not the
delay simulation is enabled.

Put the interfaces in an L2 bridge group, or they won’t be in promiscuous
mode...
Here’s a config that I use a bunch:
set int l2 bridge FortyGigabitEthernet86/0/1 1
set int state FortyGigabitEthernet86/0/1 up
set int l2 bridge TenGigabitEthernetd/0/0 1
set int state TenGigabitEthernetd/0/0 up
bin nsim_configure delay 10 ms bandwidth 10.1 gbit packet-size 128
bin nsim_enable_disable FortyGigabitEthernet86/0/1 TenGigabitEthernetd/0/0

Hello Dave, doesn't appear to forward. My ARP packets are not being forwarded.
I assume in this cross connect any packet in an interface is sent out the
other interface and vice versa?
Anything special needed in the startup.conf?

Subject: [vpp-dev] WRED
I am looking to setup vpp with WRED. I am not sure how the WRED profiles are
configured. I have hqos with 2 interfaces working in a bridge-domain and now
want to enable WRED.
My overall goal is to simulate the Linux tc "traffic control" application to
run impairments such as delay and packet loss.
